Description

technical field

[0001] The invention belongs to the technical field of intelligent color-changing displays, and in particular relates to a full-chromatogram electrochromic display and a preparation method thereof. Background technique

[0002] Human beings have always been interested in the phenomenon of color change. On the one hand, colors make human life more colorful; on the other hand, people use various colors as signs to convey information. Electrochromic materials are materials that change color under the action of an applied electric field or current. As a smart material, it can adjust its absorption of light in a wide range, and has the characteristics of low energy consumption, memory storage, and stable performance. Therefore, the application of electrochromic materials is in line with the sustainable development of the national economy and scientific development. Strategic requirements. In addition, with the gradual enhancement of people's awareness of energy...
